ruby - Make space to dash with regexp -


I've got a Sinatra app where I'm planning to make a Fried-url when I fly. I have found a regexp function which looks like this, but it will not change 'empty space' from 'dash', '' to '-'. 

  def self.make_slug (title) title.downcase.gsub (/ /, '-'). Gsub (/ [^ a-z0- 9 _] /, ''). Squeeze ('-') termination

Thanks in advance!

Update

Now I am trying to change to o in another o, my code looks like this but won 'work' any idea? 

  gsub (/ [åä] /, 'a') gsub (/ [ö] /, 'o')
"-" with "" are changing, and then everything changes but with a-Z0-9 _ (Thus, "-") "". Include in the list like [^ a-z0- 9 _-]

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
